In relation to the disposal of radioactive waste, the multibarrier containment concept envisages a combination of natural and engineered barriers acting to ensure that radionuclides in the waste are isolated from the human environment. The aim is tha

Calculations of radiological risk are required to assess the safety of any potential future UK deep underground repository for intermediate-level and certain low-level solid radioactive wastes. In support of such calculations, contaminant movement an

High purity cadmium springs have been creep tested between −6 and 36 °C at stresses below 5 MN/m2. The results have indicated that the creep mechanism is probably that of grain boundary diffusion creep, but with two modifications: first that subgr

The microstructural changes accompanying diffusion creep in a magnesium –0·62 wt.% Mn alloy have been examined. Up to ∼20% strain, deformation takes place by the formation of precipitate-denuded zones with accommodation by grain boundary sliding

Two-phase alloys have creep rupture lives which are many orders of magnitude longer than those of the pure parent metal at the same stress and temperature. This could be caused by the intergranular precipitates adversely affecting the ability of the

Creep has been investigated in Cu–Ni and Cu–Sn alloys in the region where the process is controlled by grain-boundary mass transport. The addition of Ni to Cu causes a reduction in the rate of creep and this is interpreted in terms of the change

A comparison of the creep behaviour of sintered magnesium powder and magnesium prepared by conventional methods has been made. Sintered material has a higher strength and quite different creep characteristics, which have been attributed to the presen
